如果在预处理过程中出现error：stray’\243’in program时 1.可能在给变量起名时用了汉字 2.存在汉语标点 在我用的codeblocks中这个很容易发现的，如果是英文字符字符会变成其他颜色，所以要解决这个问题只需要去查看字符的颜色就可以了 标题3.可能存在全角字符 windows10系统可能会误操作把半角符转换为全角符 全角英文就是这样 ａｂｃｄｅｆｊｈｉｇｋｌｍｎｏｐ 半角英文这样 abcedfjhigk 这时只需要shift+空格就可以了 ————————————————

报错的意思是c/c++中的产生了编译错误。   该错误是指源程序中有非法字符，需要将非法字符去掉。一般是由于coder使用中文输入法或者从别的地方直接复制粘贴代码造成的。代码中出现了中文空格，中文引号， 各种中文标点符号都会出现，简单修改一下就OK了。 解决方法： 1.把出错行的空格及其前后空格删掉重新打一下试试。 2.把明显和其他标点符号颜色不同的改掉。（大部分编译器都有颜色识别） ...
c语言中stray‘\243‘in program

首先解释下这句话的意思 遇到了ASCII值243的非法字符 代表编译器在编译源文件时遇到了不可识别的非法字符。其值为ascii码值243。 这一个值并不在合法的英文字符范围(0~127)范围内，所以一般都是由于误输入造成的。出现这类问题时，需要根据提示错误的行数，找到对应行，然后重点查找以下几个方面： 1 是否存在汉字。大多数的C编译器并不识别汉字，所以变量名中不要使用汉字。 2 是否存在汉语标点。这种情况是最常见的。C语言要求所有的符号必须是英文半角符号，当有中文标点符号出现时，就会有此类错误出现，比如逗
